What effect is produced on a wire loop when it is placed in a magnetic field?

When a wire loop is placed in a magnetic field, it experiences a torque due to the interaction between the magnetic field and the electric current flowing through the wire. This phenomenon is rooted in the principles of electromagnetism, particularly Faraday's law of electromagnetic induction and the Lorentz force law.

As a conductor carrying an electric current is situated in a magnetic field, the magnetic forces exerted on different segments of the wire create a net torque. This torque causes the loop to rotate about an axis, which can be utilized in applications such as electric motors. The direction of the torque is determined by the right-hand rule, which illustrates how the magnetic field interacts with the current in the wire.

The other options do not accurately capture the primary effect of placing a wire loop in a magnetic field. The loop does not remain stationary if a current is present; rather, it will be influenced by the magnetic field. Heating may occur due to the resistance of the wire and the current flowing through it, but it is not the direct effect of placing the loop in the magnetic field itself. Lastly, a short circuit implies an unintended low-resistance path that allows current to flow uncontrollably, which is not a typical result of simply placing a wire loop in a
